An oscillation theorem for second-order nonlinear differential equations of Euler type

Abstract
We consider the nonlinear equation t^2x''+g(x)=0 , where g(x) satisfies xg(x) > 0 for x = 0, but is not assumed to be sublinear or superlinear. We study the problem whether all nontrivial solutions of the equation are oscillatory in some critical cases.
